Questions Helen has answered

Explain the difference between spatial and temporal summation at a synapse.

-Spatial summation occurs when multiple presynaptic neurones together release enough neurotransmitter (e.g. acetylcholine) to exceed the threshold of the postsynaptic neurone. For example, neurone A and neurone B may individually release insufficient neurotransmitter but when these quantities are combined, threshold may be exceeded and an action potential generated. 

-Temporal summation occurs when one presynaptic neurone releases neurotransmitter many times over a period of time. The total amount of neurotransmitter released may exceed the threshold value of the postsynaptic neurone. The higher the frequency of the action potential the more quickly the threshold may be exceeded.

How can bacteria become resistant to antibiotics and how can doctors reduce the number of bacteria that become resistant?

-A mutation in a pathogen may produce a new strain. This new strain may become resistant to an antibiotic through natural selection. The new strain may spread rapidly as the individual is not immune to it and the antibiotic does not kill the bacteria. An example of a resistant strain is MRSA

-Doctors can reduce the number of bacteria that become resistant by encouraging patients to complete the whole course of antibiotics, not prescribing antibiotics for viral infections and only prescribing antibiotics for more serious bacterial infections.

How should I approach my extended project?

- Get started as early as possible- As soon as you have a potential topic, start researching and gathering information!  

-Make sure to attend meetings with your mentor- They have a lot to offer and a consistent level of engagement can help boost your mark. 

-Communicate with your peers- As such an independent project, talking to others also undertaking the project can be very helpful. 

-Don't leave it until the last minute- As such a large project, leaving it until the last minute, when you have other revision to do is likely to cause a large amount of stress and may harm your other subject grades. 

-Make sure to write about it on your personal statement- Universities look highly upon such a self-directed and independant project and it may be an interesting thing to talk about at an interview. 

-Make sure you are fascinated by the topic you pick- The project will take most of the year so make sure to pick a topic that you won't lose interest in. I would recommend picking a topic you already know quite a lot about and would be prepared to research at home. 

-Take note of your references as you go along- If left until the end this can be time consuming and may result in inaccuracies. 

-Enjoy it- The EPQ should be a break from your other A-level subjects and a chance to pursue your own interests!
